I frequently get segfaults that seems to be related to vmanip calc_lighting.

Is this something that needs to be fixed in the engine or could be a problem with a mod? It happens in adventuretest (https://www.github.com/bremaweb/adventuretest) and it seems to happen mostly because of vmanip used in mg_villages and/or mg/dungeons.lua
Any help is appreciated.
